So, my ex and I had a pretty open relationship. We shared everything. From who we want to fuck, to watching porno videos of her with her ex boyfriends. We were doing a lot of nasty things but we were always honest with each other.
She was living in another city where she was studying. I would go to her every 2 or 3 weeks on a few days, and we would mostly spend them fucking, eating and sleeping. She had a horny neighbour who was always hitting on her. She was kinda lonely when I wasn’t there, and she really liked him. On one occasion he picked her up when she was coming back from a night out. After they both went to their apartments she got a message from him. It was a dick pic, and it made her really horny. She forwarded me a pic of his dick (it was pretty bigger than mine, around 8”, cleanly shaved and circumsized) and asked me what to do. I gave her a pass since she really fancied him, and told her to call him over to her apartment. He came few minutes after, and she sucked his dick. He came in her mouth in a minute or two, and nervously left.
